Congratulations to Nick. At bare minimum, he was as good an all-around player as we've seen. Still, restricting attentions to those of his era, both Sigel and Lassiter were probably comparable as all-around cueists. If three cushion billiards is included in the assessment, Harold Worst is also in the conversation.
Whether he's better than a) SVB (3 DCC Master of Table, World 9ball Champ, World 8ball Champ), b) Fedor Gorst (3 Derby City Master of Table, World 9ball Champ), or c) Josh Filler (Derby City Master of Table, World 9ball Champ, World 8ball Champ, American 14.1 Champ, European 14.1 Champ, World Games Gold Medalist) is a debate for another day.
Bottom line here, though, is that Nick was an all-around player of the highest pedigree and this recognition was hard earned and is well deserved. Bravo, Nick.
